LOCK RETAINER Filed July 8, 1948 i INVENTOR.

tially overlying the lock-receiving aperture I4 to provide means oredges for engaging the body I8 of the lock I6. These body engaging edges29 and 3| are adapted to embrace the lock body I8 within recesses orgrooves 36 and 33 provided on opposite sides of the lock body I8. Thearched configuration of the head provides cam surfaces along the margins29 and 3| of the clamping head 28, these cam surfaces enabling theretainer plate 26 to draw the lock assembly axially into mountedposition on the panel 26.

Along one margin of the retainer plate 26 are two laterally extendingengaging ears or tabs 32 and 34. These tabs are positioned oppositeapertures 36 and 38, respectively, which are provided in the inner panel31 of the door unit. When engaged by a tool such as a screw driver 46,the

retainer plate 26 may be rotated to lock-receiving position (as inFigure 2), or likewise, to retaining position (as in Figure 3), asdesired. By this arrangement the necessity of removing the inner panel31 to disengage the mounting means is eliminated and mounting ordismounting of the lock structure on the panel is accomplished withgreat facility. Ears or tabs 32 and 34 preferably are recessed by havinga concave or angular face so that positive engagement of the surfacewith a tool such as screw driver 43 is assured, as seen in Figure 3.Furthermore, by forming the tabs 32 and 34 in this manner, a strongertab portion is provided. When the lock retainer is mounted on a verticalpanel the retainer plate 26 is preferably mounted with the clamping head28 overhanging the aperture I4. This insures retention of the lockstructure in the panel by the retainer plate 26 despite vibrations andother forces which might tend to cause disengagement of the retainermember 26 from the lock body I8.

The base plate I2 is provided with stops 42 and 44 for limiting thepivotal movement of the retainer plate 26 relative to the base plate I2.Complementary locking detents 46 and 48 are provided on the base plateI2 and retainer plate 26, respectively, to releasably hold the lockingplate in lock-receiving or looking position.

In operation, the retainer plate 26 is moved to lock-receiving position,as shown in Figure 2, to .permit insertion of the lock body I8 throughthe apertures 22 and I4 in the outer panel and base plate, respectively.Shoulder or flange 11 of the lock body I8 engages the outer surface ofthe panel 26. A tool such as screw driver 40 is then inserted throughaperture 36 and the retainer plate rotated about pivot 24 toward lookingposition. As rotation progresses, theinner margins 29 and 3| 0f theretainer plate 26 engage the shoulders provided by the recesses 36-33 inthe lock body. The lock assembly is retained against rotative movementby the clamping action of the oppositely positioned engaging margins 29.and 3I of the clamping head 28 and the oppositely'positioned grooves 30and 33 of the lock body I8. The arched margins 29 and 3| of the clampinghead 28 draw the lock structure axially to seat the flange I! of thesleeve I8 against one surface of the panel and to retain the lockstructure in this position.

Figure 6 shows another form of lock retainer II'Ia contemplated by theinstant invention. Lock retainer IIla comprises a base plate IZa and aretainer plate 26a pivotally mounted on the base I2a by rivet member24a. The margin of aperture I4a of the base plate [2a is provided with aseries of spaced keyways or slots 56. The base plate I2a about theperiphery of the aperture 4 14a is provided with pairs ofcircumferentially extending arms 52 and 54 which have formed thereonportions adapted to coast with the edges of panel 26a. defining keyways56 for securing the base plate 12a to the panel 26a. Arms 54 arehook-shaped and adapted to be hooked over a radially extending edge ofkeyways 56 to engage both surfaces of panel a upon rotationof the baseplate relative to the panel 20a, after which the L-shaped resilient arms52 latchingly engage the opposite radially extending wall of the keyways56. The arm 52 is necessarily resilient to permit engagement of thehook-shaped arm 54 with the panel 23a prior to the registration of theflange 58 of the L-shaped arm 52 with the keyways 6%. Retainer plate 26ahas a resilient arm 64 sheared or struck from the retainer plate.

' This resilient arm has a dimple or detent 66 which is adapted toengage a complementary portion 46a provided in the base plate I2a forholding the retainer plate in lock-receiving position. A second dimplesimilar to portion 46a, not seen in Figure 6, is engaged by detent 66 ofthe retainer plate to hold the plate in locked position relative to thebase plate'l2a.

In Figure 7 is shown the base plate I2 having a plurality of tabs 66 and62 to engage opposite walls of keyways in the panel 23. This is apreferred form where the lock retainer is mounted or arms 32 or 34 onthe retainer plate 26 and apertures 36 and 38 in the inner panel affordssimple means for operating the look retainer structure when it issecured to the panel and eliminates the burden of gaining access totheback'structure by removal of panel sections etc.

The arching of the clamping head of the retainer 1 plate provides a verysturdy clamping head, and

at the same time provides the cam surfaces essen tialfor securing thelock against'axial movement I on the panel.

The C-shaped construction of the clamping head afiords positive lockingof the fastener against rotative movement relative to the panel. Thelock retainer mounting provides a unit which remains in operativeposition at all times, and in addition, precludes the possibility ofunauthorized dislodgment of the look by vibration, tampering or jarring.

For purposes of illustration, one practical application of the retainerdevice has been shown,

namely, the application thereof to cylindrical or pillar locks.Obviously, the invention is not restricted to use in this particularfield, but is capable of many other practical applications. It

is to be understood that thisinvention should be I limited only bythe'scope of the appended claims.
